| zones of discontinuity | Concentric zone's of varying optical density in the lens of the eye, as seen in slitlamp biomicroscopy. (05 Mar 2000) |
|---|---|
| Andernach's ossicles | Small irregular bones found along the sutures of the cranium, particularly related to the parietal bone. Synonym: ossa suturarum, Andernach's ossicles, epactal bones, epactal ossicles, wormian bones. (05 Mar 2000) |
| auditory ossicles | The small bones of the middle ear; they are articulated to form a chain for the transmission of sound from the tympanic membrane to the oval window. Synonym: ossicula auditus, ear bones, ossicular chain. (05 Mar 2000) |
| Bertin's ossicles | Paired ossicles of pyramidal shape, the spines of which are in contact with the medial pterygoid lamina, the bases forming the roof of the nasal cavity. Synonym: conchae sphenoidales, Bertin's bones, Bertin's ossicles, sphenoidal turbinated bones. (05 Mar 2000) |
| muscles of auditory ossicles | The musculus stapedius and musculus tensor tympani. Synonym: musculi ossiculorum auditus. (05 Mar 2000) |
| epactal ossicles | Small irregular bones found along the sutures of the cranium, particularly related to the parietal bone. Synonym: ossa suturarum, Andernach's ossicles, epactal bones, epactal ossicles, wormian bones. (05 Mar 2000) |
| joints of auditory ossicles | The joints of the ossicular chain consisting of incudomallear joint, incudostapedeal joint, and the tympanostapedeal syndesmosis. Synonym: articulationes ossiculorum auditus, joints of ear bones. (05 Mar 2000) |
| ligaments of auditory ossicles | The ligaments connecting the ear bones with one another and with the walls of the tympanic cavity. Synonym: ligamenta ossiculorum auditus. (05 Mar 2000) |
| acromioclavicular dislocation | <orthopaedics> Disruption of the normal articulation between the acromion process and the clavicle. The acromioclavicular joint (AC joint) is normally stabilised by several ligaments that can be torn in the process of dislocating the AC joint). See: acromioclavicular sprain. (27 Sep 1997) |
| patellar dislocation | <radiology> most common in young girls, (genu valgum, patella alta, quad mm deficiency more in girls), lateral dislocation, spontaneous reduction, recurrent dislocation, fracture associated in 5-10% (12 Dec 1998) |
| perilunar dislocation | Dislocation of carpal bones around the lunate, which remains in relation to the radius; distinguish from dislocation of lunate, Kienbock's dislocation. (05 Mar 2000) |
| perilunate dislocation | <radiology> Lunate remains aligned with radius, capitate dislocates (usually posteriorly), more common than lunate dislocation (radial-lunate ligaments stronger than lunate-capitate ligaments), associated with scaphoid fractures (75%) = transscaphoid perilunate dislocation (12 Dec 1998) |
| chopart fracture-dislocation | <radiology> A fracture-dislocation occuring through the hindfoot-midfoot joint (i.e., tarsonavicular and calcaneocuboid joints) (12 Dec 1998) |
| closed dislocation | A dislocation not complicated by an external wound. Synonym: simple dislocation. (05 Mar 2000) |
| compound dislocation | Synonym: open dislocation. (05 Mar 2000) |
